CVE-2016-1000236

Name of the Vulnerable Software and Affected Versions Node-cookie-signature versions prior to 1.0.6

Description The issue is related to a timing attack due to the use of a fail-early comparison instead of a constant-time comparison in the cookie-signature module. This type of comparison allows attackers to exploit miniscule timing differences, providing per-character feedback on the correctness of a guess. As a result, the entropy gained from increased secret length is reduced, enabling an attacker to guess the secret in a significantly lower number of attempts.

Recommendations Update to version 1.0.6 or later to resolve the issue.
